SOFTWARE ENGINEERING

Detailed explanation-1: -It enables multiple operating systems with dierent congurations to run on a physical machine at the same time. A software layer called virtual machine monitor (VMM) or hypervisor is required to run the virtual machines on a system.

Detailed explanation-2: -Infrastructure as a Service (IaaS) is a business model that delivers IT infrastructure like compute, storage, and network resources on a pay-as-you-go basis over the internet. You can use IaaS to request and configure the resources you require to run your applications and IT systems.

Detailed explanation-3: -Virtual infrastructure components By separating physical hardware from operating systems, virtualization can provision compute, memory, storage and networking resources across multiple virtual machines (VMs) for greater application performance, increased cost savings and easier management.

Detailed explanation-4: -Virtualization enables cloud providers to serve users with their existing physical computer hardware; it enables cloud users to purchase only the computing resources they need when they need it, and to scale those resources cost-effectively as their workloads grow.
